Hey Wogeroo...
Your post is ancient, and you've probaby moved on, unless you are like me and have put off fixing the vent window pivot for 14 months...my 65 has the same problem. I saw in LMC catalogue they sell those pins...I am about to order one for mine. I IMAGINE the old one that rusted off needs to be driven out of the vent frame. I have no clue how to remove the glass or get it back in, but it will likely be evident as the job progresses...I hope. I am pretty sure the 65 manual (supplement) shows removal of vent window...and that silly 1960-66 Chevy Truck Assemble manual probably has some hard to decipher diagram. best of luck-Jerry Mann
